HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 242,564, dated June 7,1881.

Application flied February a, 1881. (Model.')

To all whom it may concern:

Be it known that I, LOUIS H. SHOLDER, of Cleveland, in the county I of(Juyahoga and State of Ohio, have invented certain new and usefulImprovements in Hose-Couplings and I do hereby declaredhe following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawi'n gs,

which form part of this specification.

My invention relates to hose-couplings; and it consists in soconstructing a hose-coupling that it can be manufactured much cheaperand at the same time be just as serviceable in every respect as any ofthe more expensive ones now in use. It is also much more easilymanipulated, and can becoupled in an instant without the use of a wrenchor any like tool.

In the drawings, Figure 1 is a longitudinal sectional view of mycoupling, having screwthreads formed on the male and female parts toadapt them to beattached to the common screw-coupling now in use. Fig. 2is a longitudinal sectional view of my coupling, showing it attacheddirectly to the hose. Fig. 3 is a plan view, showing the openings of thefemale part of my cou iiling; and Figs. 4 and 5 are isometric views ofthe male and female parts, showing them in position tobe coupled.

Like letters of reference represent corresponding parts in the severalfigures.

A represents the male part of my coupling, and is provided with lugs a,and also spigot b and shoulder c. As shown in Fig. 1, in some cases Iprovide thispart with afemale thread, which corresponds with the malethread of the common scrmvcoupling, so that it may be readily attachedto hose having said male screw part.

B represents the female part of my coupling, which is provided withopenings 63 and inclines c, said inclines being roughened. f is anannular rubber packing. It will be seen by reference to Fig. 1 of thedrawings that I also provide this part with a screw-thread adapted tocorrespond with the female thread of the common screw-coupling, so thatit also may be readily attached to hose having said female screw part.

The operation ot niy device is as follows:

The male part A of my coupling is attached to one end of a length ofhose, either directly, as shown in Fig. 2, or by means of the male partof the common screw-coupling, as the case may be. Ihe female part B isattached to one end of the length to be coupled with the first length,either directly, as shown in Fig. 2, or by means of the female part ofthe commonscrew-coupling, as shown in Fig. 1.

Now, to couple thcparts the lugs a arebrought opposite the openings d,which are large enough to admit them. After being entered the parts Aand B are turned in opposite directions, and

the lugs a coming in contact with the inclines c, said inclines bringthe shoulder 0 against the packing f, which, being pressed tightlybetween shoulder c and its seat on the female part of the coupling,forces it against the outer circumference of spigot I), and also theinner circumference of the female part of the coupling, thus forming aperfectly tight joint.

It will beseen that I have provided the inclines c with roughened faces.My reason for this is to keep the lugs a from slipping back after beingonce turned in place upon said inclines, the rubber packingserving toforce the sharp side of the lugs atightly againstthe said roughened faceof the incline and hold it there. v

It will also be seen that my coupling can be manufactured much cheaperthan many now in use, as the only work on them after they are cast is toclean them, the annular rubber packing, when compressed between theshoulder cam]. its seat in the female part of the coupling, fillingevery irregularity of the surfaces with which it comes in contact, andhence forming a perfectly tightjoint.

What I claim isk 1. A hose-coupling, the same being provided on its maleportion with lugs a and on its female part with inclines c, saidinclines having a roughened face, substantially :as described.

2. In a hose-coupling, the combination of the male part A, with its lugsa, shoulder c, and spigot 11 of the female part, said female part beingprovided'with inclines c and washer f, substantially as described.

3. A hose-coupling substantially as described, one part of saidhose-coupling being 'screvmhreaded in such a manner that it may to thisspecification in the presence of two subbe at ached to the male part ofthe common scribing witnesses. 1

scre -e0upling, and. the other part; being adapted to be attached tothefemale part of said common screw-coupling, substantially asWitnesses:
